Anthropic's survival depends on Claude Code performing as well as it can, by all metrics.
If the Very Smart People working on CC haven't integrated a feature or put text into the System Prompt, it's probably because it doesn't improve performance.
Put another way: The product is probably as optimized as it can get when it comes out the box, and I'm skeptical about claims otherwise without substantial proof.
Lately, I lean towards keeping a vanilla setup until I’m convinced the new thing will last beyond being a fad (and not subsumed by AI lab) or beyond being just for niche use cases.
For example, I still have never used worktrees and I barely use MCPs. But, skills, I love.
That said, most of this repo is solving the wrong problem. "Answer before reasoning" actively hurts quality, and the benchmark is basically meaningless. But the anti-sycophancy rules should just be default. "Great Question!" has never really helped anyone debug anything.
So the market kind of works in this instance.
Even when one helps, you're still betting it won't be obsolete or rolled into the defaults a few weeks from now.
So you could run these 'cure-alls' that maybe relevant today, as long as you are constantly updating your md files, you should be ahead of the curve [lack of better term]
